Affymetrix Porcine Genome Array (porcine)
Description
Brucella suis infects macrophages and dendritic cells. Wild boars act as reservoirs and carriers of Brucella suis biovar 2, and there is evidence that wild boar can be the main source of infection for domestic pigs through the venereal route. Transmission through this route could be an important path for disesease dissemination. The result from this study will contribute to the overall understanding of the molecular pathogenic mechanisms involved during Brucella suis infection in European wild boar.

Description
Anaplasma phagocytophilum infects a wide variety of host species and causes the diseases granulocytic anaplasmosis in humans, horses and dogs and tick-borne fever in ruminants. The objective of this research was to characterize differential gene expression in wild boar naturally infected with A. phagocytophilum by microarray hybridization using the GeneChip Porcine Genome Array

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
We have used microarray technology to identify the transcriptional targets of Rho subfamily GTPases. This analysis indicated that murine fibroblasts transformed by these proteins show similar transcriptomal profiles. Functional annotation of the regulated genes indicate that Rho subfamily GTPases target a wide spectrum of biological functions, although loci encoding proteins linked to proliferation and DNA synthesis/transcription are up-regulated preferentially. Rho proteins promote four main networks of interacting proteins nucleated around E2F, c-Jun, c-Myc, and p53. Of those, E2F, c-Jun and c-Myc are essential for the maintenance of cell transformation. Inhibition of Rock, one of the main Rho GTPase targets, leads to small changes in the transcriptome of Rho-transformed cells. Rock inhibition decreases c-myc gene expression without affecting the E2F and c-Jun pathways. Loss-of-function studies demonstrate that c-Myc is important for the blockage of cell-contact inhibition rather than for promoting the proliferation of Rho-transformed cells. However, c-Myc overexpression does not bypass the inhibition of cell transformation induced by Rock blockage, indicating that c-Myc is essential, but not sufficient, for Rock-dependent transformation. These results reveal the complexity of the genetic program orchestrated by the Rho subfamily and pinpoint protein networks that mediate different aspects of the malignant phenotype of Rho-transformed cells

Description
Effect of the overexpression of the oncogenic form of the Vav2 protein in the NIH3T3 cell line under serum deprivation conditions. oncovav2-transformed NIH3T3 cells grown in serum-deprived medium (Vav2SD) are compared to the parental NIH3T3 controls under the same growth conditions (ContSD). Vav2SD cells are also compared to the oncovav2-transformed NIH3T3 cells growing exponentially and the NIH3T3 growing exponentially.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Yeast strain BY4741 was grown overnight at 30C in YPD rich media. The yeast culture was diluted to an OD600 of 0.1 using fresh YPD media and further grown until an OD600 of 0.2. Then, alpha -factor mating pheromone (GenScript) was added to a final concentration of 10 uM to allow cell synchronization at G1 phase. After 2.5 h, the alpha-factor was removed by harvesting the cells for 10 min at 6000 rpm and decanting supernatant. The arrested cells were inoculated in fresh YPD rich medium to be released from G1-arrest. Samples were collected at 0, 30, 40, 50, and 70 mins, 7.5 ml samples were collected for RNA extraction while 40 ml samples were taken for nucleosomal DNA preparation and for flow cytometry (FACS). Samples for RNA isolation were collected by pipetting the culture directly into 15-ml Falcon tubes containing 7.5 ml of icy-water to quickly chill the cells. Cells were harvested by spinning for 3-4 min at 6000 rpm, frozen in liquid N2 and stored at - 80C. Total cellular RNA was extracted using the RNeasy kit (Qiagen), following the manufacturer’s instructions with the spheroplasting protocol. Purified RNA samples were quantified by Qubit fluorometer (Invitrogen, Inc.) and Nanodrop spectrophotometer (Thermo Scientific, Inc.). The total RNA was hybridized to Affymetrix GeneChip Yeast Genome 2.0 arrays for gene expression analysis.

Description
Loss of function of the tumor suppressor BRCA1 (Breast Cancer 1) protein is responsible for numerous familial and sporadic breast cancers. We previously identified PABP1 as a novel BRCA1 partner and showed that BRCA1 modulates translation through its interaction with PABP1. We showed that the global translation was diminished in BRCA1-depleted cells and increased in BRCA1-overexpressing cells. Our findings raised the question whether BRCA1 affects translation of all cytoplasmic cellular mRNAs or whether it specifically targets a subset of mRNAs.

Description
Substantia nigra pars compacta (SNpc) is highly sensitive to normal aging and selectively degenerates in Parkinson's disease. However, ventral tegmental area (VTA), a region adjacent to SNpc, is less affected in PD. Until now, molecular mechanisms behind VTA aging have not been fully investigated using high throughput techniques.
